IPROVEMENT IN LATHES.`

Specification forming part of Letters Patent No. 113,798, dated April 18, 1871 antedated April 10, i871.

We, Jol-IN F. C. RIDER, of South New Market, in the State of New Hampshire, and EM- Eason P. BRoWnuLL, of Prevalence, Rhode Island, have invented a Ilevce for Boring and Smoothing the Ends of Spools, of which the following is a specication:

Figure I, top view of the machine; Fig. II, side view of the same with the spool in place and the cutters smoothing the ends, the auger, combined with one of the cutters, having bored into the end of the spool; Fig. III, side and v face view of the cutter I-I 5 Fig. IV, side and face ward the fixed. arm, E, the ,crank yaghich turns the drum upon which wind the cords operating the levers B lo; l' f I rIhe machine operates aslvggolicws: A piece of stock from the rougher, A:sawed off about the length of a spool, is held against the fixed arm O ofthe spool-clamp, and` by pressing with the foot upon the lever by the action ofthe levers the arm G is brought :toward the ixed arm Gr, and these, pressing against the stock, hold it in its place. lThe crank F is turned, and the-levers B B, acted upon by the cords which are wound about the drum, slide the revolving spindles, and consequently the cutters H and I are brought toward each other and in contact with the spool stock, the auger U first piercing into the head of the stock its lfull llength before the cutterlI smooths the ica( The drum and cords attached. to the crank E are so adjusted that the cutters approach each other and cut away the stock till the exact length of a spool is acquired. The hole is bored in the end of the spool that it may be thus held upon the spindle of the winder when it receives the thread.

The great art in this part of the process of spool-making is to have the hole in a spoolhead exactly at right angles to the line oli' the face of the spool-head; otherwise irregular winding of the thread is caused and the spool is rendered Worthless.

By the invention above described the auger is fixed in such a position that it must always make a hole at right angles with the face.

The cutters I-I and I consist of a spindle and head made of fine steel. The head is beveled each way from the center line toward the circumference, and incisions are made into the head so that the knife-like cutters are formed by the beveled edge, as shown in Figs. III and IV. lnto the head of one of the cutters an auger is placed.

lWe are aware that somewhat similar machines have been used for the purpose of inakin g aWl-handles, buttons, and other similar articles. Ve thereforedistinctly disclaim the several parts of the device as separately considered-5 but What we do claim is- The improved spool-heading and boring apparatus herein described, consisting of the reciprocating spindles X, cutter-head H, combined cutter-head and auger I, leversF and B, and spool-clamp D C, with ljaws parallel with the spindles, the whole being combined and operating as and for the purposes specified.
